looking for professionals from Mumbai India- for doing following project its simple college project not required in professional way. current requirement is Q2: Create two web forms in your application which must contain different fields to take user input corresponding to the defined entities/tables created for the Q1. For example, regarding an online music store application, one form should ask the user to input all information related to Albums while the second form should ask the user to input all information related to the Singers. Create a SpringBoot application deployed on port 8080 which receives form data via POST request and stores the submitted data (e.g., in a JSON file) in the resource folder of your application.

You must create at least two separate files for each of the two web forms submitted to receive user input. All subsequent entries by the users for forms submission should be appended in the corresponding JSON files. Q3: Deploy another SpringBoot service on Port 8081. Expose endpoints which receive a GET request from your front-end application and returns a JSON object containing a list of objects (items/products/albums) depending on your application. These objects should correspond to your entities stored in JSON objects from Q1 and Q2.

You can read files either at application start-up or on each request. Data received from the SpringBoot service should be displayed on your front-end application in a tabular form or any other appropriate format. Q4: Please extend the SpringBoot Service from Q3 so you can fetch additional data from the second JSON file on the relevant object selection. For example, in Q3 when you have displayed all data from the Albums files, on clicking the foreign key attribute (e.g. Singer ID) , you should send Singer ID as a query or path parameters to the new controller endpoint, find relevant data and display it to the user.

Introduction

In the realm of web development and backend systems, SpringBoot has emerged as a versatile and efficient framework for building scalable Java applications. This project aims to create a simplified music store application that involves creating web forms for data input, persistent storage in JSON files, and RESTful services to retrieve and display data dynamically. The project is designed primarily as a college-level exercise, emphasizing understanding of web forms, file handling, REST APIs, and entity relationships within SpringBoot.

Design Overview

The system comprises two main parts: a front-end interface with forms for user data input and two backend SpringBoot services that manage data storage and retrieval. The first SpringBoot application, running on port 8080, handles form submission—collecting album and singer information—and stores the data in JSON files within the resource folder. The second SpringBoot application, running on port 8081, exposes REST endpoints that supply the stored data in JSON format upon request, enabling dynamic display on the client side.

Implementation Details

Form Creation and Data Storage

The forms are developed using simple HTML with appropriate input fields to capture details related to albums and singers. For example, the Album form might include fields such as Album Name, Release Year, and Singer ID, while the Singer form includes Singer Name, Genre, and Singer ID. Upon form submission, a POST request is made to the SpringBoot server, which processes the data and appends it to the respective JSON files (albums.json and singers.json). This approach ensures persistence without the need for a complex database.

Data appending is handled carefully to preserve existing data, by reading the current JSON content, adding the new record, and writing back to the file. This operation is performed each time a user submits new data via the form. To facilitate this, SpringBoot controllers are developed with appropriate endpoints to handle POST requests and file I/O.

SpringBoot Application on Port 8080

The first SpringBoot application includes two endpoints corresponding to the two forms:

  • /addAlbum - POST endpoint to receive album data and store it in albums.json
  • /addSinger - POST endpoint to receive singer data and store it in singers.json

The server also serves the HTML forms to the users, enabling the data entry through a simple web interface. This separation ensures modular handling of form submissions.

Creating RESTful Services on Port 8081

The secondary SpringBoot application initializes on port 8081. It exposes GET endpoints such as:

  • /albums - returns a list of all albums stored in albums.json
  • /singers - returns a list of all singers stored in singers.json
  • /albums/{id} - returns specific album details based on Album ID or other entity identifiers
  • /singers/{id} - returns specific singer details

This implementation allows the frontend to request data dynamically, which can be displayed in tabular format or any informative layout. File reading can be optimized to occur during startup or on-demand in response to requests.

Enhancement — Fetching Related Data

To implement the feature of fetching related data, when the user views a list of albums and clicks on a foreign key like Singer ID, a new request is triggered to fetch corresponding singer details from the second JSON file. The endpoint receives the Singer ID as a path or query parameter, searches the singer data, and dynamically returns the relevant information for display. This method emphasizes understanding of relational data handling in a primarily file-based storage system, simulating database relationships.

Conclusion

This project encapsulates key concepts of web form creation, file handling, RESTful service development, and relational data management in SpringBoot. Though simplified for college use, it provides foundational understanding applicable in real-world scenarios, including data persistence, API design, and client-server interaction.
